IMHO, maybe you can consider a SR325x. It's an easy choice, everything will sound great, like the SR80x, no matter the source/amp.
Sometimes I think the RS2x it's a more niche heaphone, for advanced audiophiles that knows about amplification, dacs, etc.
I'm having a lot of fun with mine, but sometimes I think everything is very stiff depending the recording. The unforgiving thing. Because of this I'm using a lot the TrueBass button on my iFi Zen Dac. With my 80x and 325x I don't need it. BUT somedays I can enjoy the RS2x without the TrueBass.
I made a bad joke here (deleted) about a friend who was socked about the RS1x souding awfull for him - but it's truly understandable.
Going up in the Reference Series seens a easy choice and more ease to be pleased. I view the Reference Series now for advanced and hardcore Grafo fans.
But truth be told, I love hanging out with all my different Grado, rotating depending on the mood.
